SPECIFIGATION forming part of Letters Patent No. 451,213, dated April 28, 1891.

Application filed November 6, 1890. Serial No. 370,526. (No model.)

To (1.1] (071 0721 it 712 051 concern/r die it known that I, GRAN vunnr 'l.. Sumner, of Townsend, county of Middlesex, State of Massachusetts, have in vented certain new and useful Improvements in Nails, of which the following is a specification, reference being had to the drawings accompanying and forming a part hereof, in whieh- Figures 1 and are IOPI'OI: oi wire nails embodying my improvement, and Fig. 2-; is a perspective of a cut nail also embodying" my improvement.

It frequently happens that carpenters and others who are nailing a piece of wood in place desire to secure it temporarily, but firmly, until they see that it is in the right position or until some adjoining piece is properly so a nail which may be used to secure a piece temporarily and at the same time will secure it firmly, and which may be withdrawn to change the position of the e-3 e dil and without danger of marring-ihe finish; and it consists in a double-headed nail, the lower head being of equal or less size than the upper head and in close proximity thereto, as shown and described, and as is more particularly pointed out in the claim which is appended hereto and made a part hereof.

In the aceom pan ying drawi ngsl have shown several forms of nail embodying myiuvention but it will be clear that the precise shape oi? the nail or ot the heads is not essential to my invention.

My improvement is simple and will be lead-- ily undcrstoinl from the accompanying drawings and the following description.

(1, is the shank of the nail.

i) is the upper head, and c is the lower head. The lower head should not be of largerdiam eter than the upper head, because when the nail is finally driven home the upper head should be suifieicnt in size to fill the hole made by the under head, in order that the work maybe neatly and properly finished. The upper and under heads may be connected by a short neck of loss diameter than either of the heads, so that the under head will be in close proximity to the upper head; or the neck. may be of a diameter equal to or substantially equal to that of the under head, the

obj cct bei ng toseparate the heads su'lficientlyto permit of the upper head being grasped by the claw of a hammer or other device for withdrawing the nail. The shoulder at (Z underneath the lower head is preferably sloping; but in the case of cut nails where the nail is flat and narrow it maybesquare, as shown at d.

I am aware that nails have been made with a flange tuulerneaththe head where the head was not intended to be driven into the material, and also that nails have been made with detachable heads, such as are employed for picture-nails, and I do not claim such; but

\Vhat I do claim is- A nailhaviug two heads which are in close proximity to each othe p the under head having a diameteu which is,.,equal to or less than that of; the upper head, substantially as and. 'l" or the purpose set lz'ort-lr.
